Description

The invention relates to mechanical engineering and allows you to expand the technological capabilities of the device by increasing the angle of rotation of the probe, and improve reliability. The device includes a rotating element mounted on the housing 1 in the form of a stepped axis (CO) of 5 s.

mounted on one end of the probe (U) 6 to interact with the load, and on the other a flat screen 7 interacting with fixedly mounted sensors 3. At the same end of CO 5 a ring 12 is mounted with a radial pin (C) 14 located on its outer side . C 14 pivotally connected spring-loaded rod 15, pivotally connected to the body and which is the mechanism for returning U and the screen 7 to its original position. The supplied load interacts with U 6, turning CO 5 with screen 7, which acts on one of the sensors 3. When rotating CO 5, the ring rotates, which through C 14 extends rod 15. After loading the load from U 6 from the spring-loaded rod 15 rotates through C 14 and ring 12 to its original position WITH 5.3 Il.

The invention relates to mechanical engineering technology, and specifically to devices for controlling the position of a floating product in a process line, for example, on a conveyor belt, and can be used to regulate the joint operation of transport and technological systems.

The aim of the invention is to expand the technological capabilities of the device by increasing the angle of rotation of the probe and increase reliability.

FIG. 1 shows the proposed device, side view, section; figure 2 - section aa id figure 1; on fig.Z - section bb in figure 1.

The device for controlling the position of the transported cargo contains a box-shaped body 1 (Figures 1 and 2) and a lid 2, on which contactless sensors 3 are fixed, so that their working part is placed inside the body 1. On the body 1, a hub 4 has a rotary element mounted made in the form of a stepped axis 5 transmitting movement from a probe 6 interacting with the (product) load (not shown) of the probe 6 to the screen 7 interacting alternately with the sensors 3. The probe 6 is made of round-shaped wire in the form of a fork bent in one plane and fixed flax at the upper end of axis 5 by means of a clamping film 8 with longitudinal grooves under the plug (figure 3) and a nut 9. Screen 7 can be made as a fork (with a normally open sensor version) or as a plate (with a normally closed sensor version ).

The screen 7 is located inside the housing 1 and fixed to the axis 5 by means of a washer 10 and a nut 11. On the atom, the end of the axis 5, opposite to the mounting of the probe 6, a ring 12 is installed with side flats (FIG. 2) under the pin 13 and with a radial pin 14 under rod 15 of the device for returning the probe 6 and acraia 7 and the initial position. The rod 15 is freely mounted in the opening of the longitudinal flange of the L-shaped bracket 16, which is attached by a transverse shelf through the axis 17 to the housing 1. A compression spring 18 is mounted on the rod 15, the force of which is adjusted by nuts 19. For fixing the device in the housing 1 and the cover 2 there are through holes 20 (FIG. 2). The pin 14 is located on the outer side of the ring 12 and the rod 15 is hinged to it.

The device works as follows.

The device can be installed, for example, in the place of transfer of cargo (product) From the main conveyor to the discharge conveyor (not shown). In this case, the load moved along the main conveyor in contact with the probe 6 deflects it at a certain angle, turning the axis 5 around its axis. Together with axis 5 it rotates at the same angle and screen 7, the first sensor 3 is triggered. From which the signal will go to activate the load transfer mechanism, for example, a pneumatic cylinder (not shown), from the main conveyor to the discharge conveyor. When the axis 5 rotates, the ring 12 also rotates. With the trunnion 14, squeezing the spring 18, the rod 15 moves out of the opening of the bracket 16. Moving, the load from the transmission mechanism continues to act and the probe b, which, together with the screen 7, rotates by an additional angle, and the second sensor 3, from which a signal is received to turn on the drive of the bypass conveyor. When the probe 6 is additionally rotated, the ring 12 also rotates, and the rod 15 moves with it. Compressing the spring 18 additionally. After the load is moved by the discharge conveyor, the probe 6 is released from the load on it and the spring 18 returns together with the screen 7 initial position. In this case, the device is ready to respond to the subsequent load of the main conveyor. The shut-off conveyor can be stopped by an end switch at the end of the transportation of the load.
